Note (1) Lamp current is measured by utilizing high frequency current meters as shown below:

Note (2) The voltage shown above should be applied to the lamp for more than 1 second after startup.

Otherwise the lamp may not be turned on.

Note (3) The lamp frequency may produce interference with horizontal synchronous frequency from the

display, and this may cause line flow on the display. In order to avoid interference, the lamp

frequency should be detached from the horizontal synchronous frequency and its harmonics as far

as possible.

mArms until one of the following events occurs:

(a) When the brightness becomes or lower than 50% of its original value.

(b) When the effective ignition length becomes or lower than 80% of its original value. (Effective

ignition length is defined as an area that has less than 70% brightness compared to the

brightness in the center point.)

Note (6) The waveform of the voltage output of inverter must be area-symmetric and the design of the

inverter must have specifications for the modularized lamp. The performance of the Backlight,

such as lifetime or brightness, is greatly influenced by the characteristics of the DC-AC inverter for

the lamp. All the parameters of an inverter should be carefully designed to avoid producing too

much current leakage from high voltage output of the inverter. When designing or ordering the

inverter please make sure that a poor lighting caused by the mismatch of the Backlight and the

inverter (miss-lighting, flicker, etc.) never occurs. If the above situation is confirmed, the module

should be operated in the same manners when it is installed in your instrument.

The output of the inverter must have symmetrical (negative and positive) voltage waveform and

symmetrical current waveform.(Unsymmetrical ratio is less than 10%) Please do not use the inverter

which has unsymmetrical voltage and unsymmetrical current and spike wave. Lamp frequency may

produce interface with horizontal synchronous frequency and as a result this may cause beat on the

display. Therefore lamp frequency shall be as away possible from the horizontal synchronous

frequency and from its harmonics in order to prevent interference.

Requirements for a system inverter design, which is intended to have a better display performance, a

better power efficiency and a more reliable lamp. It shall help increase the lamp lifetime and reduce its

leakage current.

a. The asymmetry rate of the inverter waveform should be 10% below;

b. The distortion rate of the waveform should be within √2 ± 10%;

c. The ideal sine wave form shall be symmetric in positive and negative polarities.

6.2 POWER ON/OFF SEQUENCE
To prevent a latch-up or DC operation of LCD module, the power on/off sequence should be as the
diagram below.

Note.

(1) The supply voltage of the external system for the module input should be the same as the definition of Vcc.

(2) Apply the lamp voltage within the LCD operation range. When the backlight turns on before the LCD operation of

the LCD turns off before the backlight turns off, the display may momentarily become abnormal screen.

(3) In case of

VCC

= off level, please keep the level of input signals on the low or keep a high impedance.

(4) T4 should be measured after the module has been fully discharged between power of and on period.

(5) Interface signal shall not be kept at high impedance when the power is on.

Note (9) Definition of TCO 99 Luminance Uniformity (Angular-dependent) (L

R

):

Luminance is measured at the center measurement position “C” on the LCD panel. The optical

axis of the luminance meter shall be aligned with the normal of the panel surface. The measuring

distance between the photometer and the surface of the panel is defined as:

Md (cm) = diagonal of the panel (cm) X 1.5 with minimum distance 50 cm.

The panel is rotated around a vertical axis which passes the center of the display by changing

the azimuthal angle to +30

°. The distance between the panel and the photometer remains

unchanged and the measured point is exact the same as the previous measured point.

The photometer is then rotated by changing its azimuthal angle with the fixed distance to the

panel. Luminance at points “L” and “R” are given:

L

min, +30

° and L

max, +30

°

The LCD panel is then rotated to another azimuthal angle to -30

°; and L

min, -3

θ

° and L

max, -30

°

are obtained by using the same procedure.

The Luminance Uniformity (L

R

) is calculated as follow:

L

R

= ((L

max, +30

°/ L

min, +30

°)+( L

max, -30

°/ L

Note (10) Definition of TCO 99 Luminance Contrast (Angular-dependent) (Cm):

Luminance contrast is measured at the center point of the LCD panel “C” along with the normal

of the display with the same distance described in Note 13. The display is then rotated around the

vertical axis by changing its azimuthal axis to +30

°; and this gives:

L

255

G.L., +30

° and L

The LCD panel is then rotated to azimuthal angle to -30

obtained by using the same procedure. The Luminance Contrast (Cm) is calculated:

10. PRECAUTIONS

10.1 ASSEMBLY AND HANDLING PRECAUTIONS

(1) Do not apply rough force such as bending or twisting to the module during assembly.

(2) To assemble or install module into user’s system can be only in clean working areas. The dust and oil

may cause electrical short or worsen the polarizer.

(3) It’s not permitted to have pressure or impulse on the module because the LCD panel and Backlight will

be damaged.

(4) Always follow the correct power sequence when LCD module is connecting and operating. This can

prevent damage to the CMOS LSI chips during latch-up.

(5) Do not pull the I/F connector in or out while the module is operating.

(6) Do not disassemble the module.

(7) Use a soft dry cloth without chemicals for cleaning, because the surface of polarizer is very soft and

easily scratched.

(8) It is dangerous that moisture come into or contacted the LCD module, because moisture may damage

LCD module when it is operating.

(9) High temperature or humidity may reduce the performance of module. Please store LCD module within

the specified storage conditions.

(10) When ambient temperature is lower than 10ºC may reduce the display quality. For example, the

response time will become slowly, and the starting voltage of CCFL will be higher than room

temperature.

10.2 SAFETY PRECAUTIONS

(1) The startup voltage of Backlight is approximately 1000 Volts. It may cause electrical shock while

assembling with inverter. Do not disassemble the module or insert anything into the Backlight unit.

(2) If the liquid crystal material leaks from the panel, it should be kept away from the eyes or mouth. In

case of contact with hands, skin or clothes, it has to be washed away thoroughly with soap.

(3) After the module’s end of life, it is not harmful in case of normal operation and storage.

RISK OF ELECTRIC SHOCK.
